The win assured Northampton of the home-field advantage in its best-of-3 playoff series, which is scheduled to open Friday. Eight teams make the district playoffs with four best-of-3 match-ups determining representatives in the department sectionals.

Northampton (12-6) can finish as the third seed, but only if East Springfield (12-5) falls to Longmeadow in its regular-season finale on Wednesday. Northampton beat East Side during the regular season, which is the tiebreaker if both finish at 12-6.

If East Side beats Longmeadow, then Northampton will be the fourth seed. Post 128 started the season at 1-3 and then was 5-5 before winning six of seven.

Kellogg took advantage of the short porch in right at Arcanum in the first, then belted a long drive to left in the fifth. Kendrick struck out nine and walked two to earn the victory.

Chris Parker, who took the loss, allowed seven hits while fanning four and walking two over six innings.

Greenfield, bound for the playoffs as well, finished the regular season 11-7.

WESTFIELD WINS: Westfield Post 124 won by forfeit over Belchertown to improve to 10-7 and secure a spot in the district playoffs.

Westfield, Ludlow and Agawam have been battling for the final two of eight playoff spots. Westfield holds the tiebreaker edge over Ludlow because of a regular-season victory, which means Post 124 can now finish no worse than as the eighth seed.

Westfield is 10-7 with 20 points with one game remaining on Wednesday against Agawam. Ludlow finished the regular season at 10-8 with 20 points. Agawam, which is 9-7 and has 18 points, has games remaining against Longmeadow (2-14) and then Westfield. Post 185 will lock down the final spot with a win in either of its last two games because it also beat Ludlow during the regular season.

TOP SEED: Amherst and East Longmeadow both finished at 14-4 and tied for first, but Amherst won the regular-season meeting which earns it the top seed.

TRI-COUNTY Easthampton 7, Teddy Bear 6 (9): Easthampton Savings Bank (7-9) scored two runs in the last of the seventh to tie the game and two more in the last of the ninth to erase a 6-5 deficit as it nipped Teddy Bear Pools (11-7).

Drew Domina and Sam Orvis had RBI doubles for Easthampton, which was outhit 10-6.

James Allison had three hits, including two doubles, for Teddy Bear Pools.

Peoples 2, Chicopee 1 (8): Mike Dombrowski scored the tying run in the top of the sixth on a double by Billy Guzman and drove home the winning run in the eighth with an RBI triple.

Todd Freeman allowed five hits to earn the win for Peoples (14-6). He struck out five and walked one. Ken Vautrin, who struck out six and walked one, allowed nine hits and was the tough-luck loser for Chicopee (8-13).
